Foundation Leaks are a common problem that can result in damage to crawlspace insulation, mold, water damage, stains on drywall, and eventual corrosion of structural supports. Often a leaking foundation is caused by improper drainage at the leaking area. If your Home Inspection turns up a leaking foundation you should first examine the guttering, downspouts, and slope of the ground surrounding the area. Sealing a foundation and installing a vapor barrier is not complicated but is is labor intensive work. The project begins with trenching the areas you will be sealing. In Raleigh and surrounding cities there is usually 2-4 feet of soil between the brick line and the foundation footing. You will need to remove the soil roughly 1 1/2 feet away from the foundations edge to properly seal and drain the area. After the sealing is done, 6mil plastic is installed, and drainage pipe has been laid, the holes are filled, and additional top soil is brought in to increase the pitch of the yard away from the sealed foundation.
